 {jeduncled ovate and oblong, flowers fasciculate 

 crowded. — One of the sp. akin to P. D. lapa- 

 thifoi. bipedal, very branched, leaves 2 or 3 

 inches long, spikes uncial or less, with a rough 

 pubescence, flowers estival incarnate, seeds

 obtuse edge. In Kentucky, Illinois &c. The 

 Discolenta scahra ft. tel. 430 is a very different 

 plant, perhaps even a Dioctis, and being smooth, 

 it was by a mistake I described it for this : it 

 must be called P. or D. punctata being quite so 

 aud probably P. ptuictatuin of Elliot.
